From the downvotes it seems like many people might be this:

I would love a suggestion for a ups that could tolerate running off my generator when the power is out for extended periods, anyone have a decently priced recommendation?

Paperless-ng (or ngx, but I don’t run that flavor)

I’m not opposed to operators trying to make money, if some server brings some feature that I find valuable, I won’t begrudge them trying to make money off it. I think the hopeful thing with federation is that when one feels that an individual server is being abusive or doesn’t like their monetization approach or is unhappy for some other reason they have the choice to go elsewhere. Competition is good.
